Summary

A new reanalysis by two NASA scientists of the three standard ice-monitoring techniques slashes the estimated loss from East Antarctica, challenging the large, headline-grabbing losses reported lately for the continent as a whole. Although not the final word, the new study shows that researchers still have a lot to learn about the vast East Antarctic Ice Sheet. Understanding the role of East Antarctica is one key to figuring out what the ice sheets, and thus sea level, will be doing by century's end.
